I have a table like this : table boocks (name varchar , return_date date)
The field return_date is not initialized :
insert into books values (name1);
insert into books values (namex);
The field return_date is updated when the books is returned like this :
update books set return_date='10-06-1999' where name=xxx;
How can i select all the item where the return_date is not updated ?
a request like this :
select * from books where return_date='' ????
(actually i initialised the return_date with the values '01-01-0001')
thank you.
